摘要: 本文利用雪地跟踪方法对哈尔滨西郊5只赤狐在1985-1986年冬季的巢区做了观察。结果表明,5只狐对巢区内各部分使用的强度是不等的,对巢区中部的某些地块使用强度要高于对外围的使用,并具有明显的方向性。5个巢区的平均活动半径为320±68米至557±82米,面积为1.44-4.O9平方公里,线性指数为1.079至2。5只狐相邻距离约1000米。

Abstract: Home ranges of five red foxes (Vulpes vulpes) in the West suburbs of Harbin were studied during the winter of 1985-1986 with the snow-tracking method.Results reverled that activities of five foxes in their horne ranges were concentrated near centers with apparent deviation in directions influenced by man.Mean radii of home ranges were 320(±68)to 557 (±82)m ., sizes were 1.44 to 4.09 km2and indices of llnearity were 1.079 to 2.Individual dlstances of five foxes averaged about 1 km.
